| Abstract: | The author introduces a kind of circuit of the direct power source of hing stability in this article.Voltage stablized control loops negative feedback are made ues of to realize constancy of outputcurrent. Working principle and basic component of the circuit are detaied in this article and main components and parameters have been analysed and calculated. The power source has a wide adjustable range and stable performance as a correcting and measuring power source of direct current meters. |
